What does it take to set up a Windows UDP connect to send/receive to Arduino?
if a program can run on a PC that passes UDP messages then what law prevents it from reading and writing to serial COM?
I have seen many programs that communicate to Windows via UDP, like UDPSpeed that shows IL-2 flight sim gauges. The app sends and receives small packets and uses the data to present graphics.
So why can't the same or similar app simply route the messages to and from a COM port instead of present graphics?
Or is there some reason why the same PC program can't do both UDP and serial COM that can do both UDP and graphics?
I can see that there will be some extra interface just to tell it which COM port to read/write but honest, the other end is there this time in IL-2 devicelink.
